Climate change research produced reasons for concern and hope in 2018
In 2018, climate scientists and energy researchers at Stanford not only documented the devastating effects of climate change on the world, but also developed new technologies to help reduce carbon emissions and considered strategies to keep societies safe as the climate continues to change. The past year brought multiple extreme events to the US, including devastating wildfires to California and deadly hurricanes on the east coast.

Understanding earthquakes is a challenging problem-not only because they are potentially dangerous but also because they are complicated phenomena that are difficult to study. Interpreting the massive, often convoluted data sets that are recorded by earthquake monitoring networks is a herculean task for seismologists, but the effort involved in producing accurate analyses could significantly improve the development of reliable earthquake early-warning systems.

Berkeley Lab researchers uncover insights into superconductivity, leading potentially to more efficient power transmission In the 1980s, the discovery of high-temperature superconductors known as cuprates upended a widely held theory that superconductor materials carry electrical current without resistance only at very low temperatures of around 30 Kelvin (or minus 406 degrees Fahrenheit).
Computer program can translate a free-form 2-D drawing into a DNA structure. Until now, designing such structures has required technical expertise that puts the process out of reach of most people. Using the new program, anyone can create a DNA nanostructure of any shape, for applications in cell biology, photonics, and quantum sensing and computing, among many others.
Naked mole-rats
Why do we use naked mole-rats? The naked mole-rat is a mammal with a truly bizarre appearance, looking like an elongated cocktail sausage with large, protruding teeth. Naked mole-rats live in large underground colonies of approximately 80 animals, which are dominated by a single breeding female, the queen; this social system is highly unusual in mammals but is similar to that commonly observed in bees and termites.

Groovy young rock stars and the Holy Grail
Will a telescopic Census of thousands of planets help to pinpoint a new Earth? For Professor Jane Greaves, such a discovery will be the 'Holy Grail' - the culmination of a career spent observing planets forming around young stars. At the heart of the study, interpreting data on raw material 'remnants' from comet collisions around stars like the Sun will be the key to success.

Window into previously unseen part of glacial environment
The Greenland Ice Sheet emits tons of methane, according to a new study showing that subglacial biological activity impacts the atmosphere far more than previously thought. An international team, including researchers from Cardiff University, camped for three months next to the Greenland Ice Sheet, sampling the meltwater that runs off a large catchment (> 600 km2) of the Ice Sheet during the summer months.

A new ’atlas’ of genetic influences on osteoporosis
Identifying more than 500 genetic determinants of bone mineral density, researchers expect to provide new opportunities for the development of novel drugs to prevent or treat osteoporosis A ground-breaking new study led by researchers from the Lady Davis Institute (LDI) at the Jewish General Hospital (JGH) has succeeded in compiling an atlas of genetic factors associated with estimated bone mineral density (BMD), one of the most clinically relevant factors in diagnosing osteoporosis.

Researchers honoured in Québec Science list of top discoveries
McGill researchers once again figure prominently in Québec Science magazine's annual list of the top 10 scientific discoveries in Quebec. For 2018, four of the selected discoveries were led by McGill-affiliated scientists.

Study shows the Sahara swung between lush and desert conditions every 20,000 years, in sync with monsoon activity. The Sahara desert is one of the harshest, most inhospitable places on the planet, covering much of North Africa in some 3.6 million square miles of rock and windswept dunes. But it wasn't always so desolate and parched.
In 2014, plant biologists with the California Department of Agriculture reported an alarming discovery: native wildflowers and herbs, grown in nurseries and then planted in ecological restoration sites around California, were infected with Phytophthora tentaculata , a deadly exotic plant pathogen that causes root and stem rot.
Tumors backfire on chemotherapy
Chemotherapy is an effective treatment for breast cancer, yet some patients develop metastasis in spite of it. Researchers at EPFL have discovered that chemotherapy-treated mammary tumors produce small vesicles that may help them spread to other organs. The study is published. Some patients with breast cancer receive chemotherapy before the tumor is removed with surgery.

UW-Madison life-expectancy paper nabs top honor from APHA
Work published by three University of Wisconsin researchers regarding decreasing the gap in life expectancy of the United States population compared to European peers, earned top honors from the American Public Health Association. The winning paper, "Meeting the Institute of Medicine's 2030 US Life Expectancy Target," was a collaboration between David Kindig, emeritus professor, population health sciences, Jenna Nobles, professor of sociology, and Moheb Zidan, PhD candidate in economics, UW-Madison.

Most hummingbirds have bills and tongues exquisitely designed to slip inside a flower, lap up nectar and squeeze every last drop of precious sugar water from their tongue to fuel their frenetic lifestyle. But in the tropics of South America, University of California, Berkeley, scientists are finding that some male hummers have traded efficient feeding for bills that are better at stabbing and plucking other hummingbirds as they fend off rivals for food and mates.
Our cutting-edge technology platforms are key enablers of research at the FMI. One of the biggest of these, with the largest number of users, is the Facility for Advanced Imaging and Microscopy (FAIM). To find out more about the facility, and microscopy in general, we spoke to the joint heads of FAIM - Christel Genoud, who is responsible for Electron Microscopy, and Laurent Gelman, responsible for Light Microscopy.
Protecting proboscis monkeys from deforestation
A 10 year study of proboscis monkeys in Borneo has revealed that forest conversion to oil palm plantations is having a significant impact on the species. Nearly half of all primate species are threatened with extinction, with habitat destruction acting as the key driving force. New research studied proboscis monkeys from 2004 to 2014, finding that the protection of swamp forests is vital for their survival.

System breaks down complex designs into easily modifiable shapes for custom manufacturing and 3-D printing. MIT researchers have devised a technique that "reverse engineers" complex 3-D computer-aided design (CAD) models, making them far easier for users to customize for manufacturing and 3-D printing applications.
